A dedication ceremony for the town’s 9/11 monument is scheduled to take place at 7 p.m. Wednesday in the public safety courtyard, 53 Main St. The public is invited and encouraged to attend. Westford’s 9/11 Committee was established to commemorate the memory of the tragic events of Sept. 11, 2001. In 2012, the committee received a section of beam from one of the World Trade Center towers destroyed in New York during the terrorist attacks. The monument, created by Westford firefighter David P. Christiana, pays tribute to all 92 Massachusetts residents who died in the 2001 attacks — including Westford residents James E. Hayden, 47, and Susan A. MacKay, 44 — and to the many first responders, police, firefighters, and emergency medical services personnel who continue to give their lives in service to others.
